Posting the start of a series that might be appreciated in the near-by future. EXECryptor is a good protector, but as time passes by, it gets deprecated. I included a few articles (3 so far) that discuss in depth some of its internals (mostly practical, not theoretical). Package contains a proof of concept (implementing SDK in a test application), our real target and the tools/scripts I used. As a side note, these articles differ (in content and thematic) from what Zool@nder posted in the other thread
Enjoy and post feedback
